CUSPIDOR.

Specification of Letters Patent.

Patented Oct. 12, 1909.

Application filed. April 30, 1909. Serial No. 493,182.

To all whom it may concern.'

Be it known that we, JAMES HENRY GREG- ORY and F oREsT Marsi-r SHUMWAY,citizens of the United States, and residents of Farwell, in the countyof Clare and State of Michigan, have invented a new and 1mproveCuspiolor, of which the following is a full, clear, and exactdescription.`

The invention is an improvement in cuspidors, and belongs to that classof such devices in which provision is made for discharging the contentsof the bowl at the bottom when the cuspidor is washed out.

The invention has in view a cuspidor of this character having sideportions hinged at the top to swing outwardly from the base, andprovided with a hopper bottom inclining from the center toward eachhinged side portion, to insure ready discharge and easy cleansing.

The invention further contemplates means normally tending to force thehinged side portions closed, anda ring, slidable around the neck of thecuspidor to spread the sides apart and hold them open against thetension of the said means.

Reference is to be had to the accompanying drawings forming a part ofthis specification,.in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a central vertical section of a cuspidor constructed inaccordance with our invention;l Fig. 2 is a cross-section through thebody of the cuspidor substantially on the line 2-2 of Fig. 1; Fig. 3 isa similar section of the cuspidor on the line 3 3 of Fig.'

' neck 11 and bowl 12, the latter having a flattened base of suiiicientextent to insure stability and provided with oppositely-arranged sideportions 13 hinged at the top, as indicated at 14, to swing outwardlyfrom the bottom, as shown in Fig. 6. The bowl is constructed with ahopper bottom 15 which inclines from the center downwardly to each ofthe hinged side portions 13. The hinged side portions 13 are extended ashort distance above the hinges, as indicated at 13a,

where they incline upwardly and outwardly from the neck, as shown inFig. 6, and incline inwardly toward the neck at each end, as shown inFig. 3. Between the extended portions 13"1 and the neck of the cuspidorare fixed V-shaped springs 16, tending to force the side portions 13closed. The springs 16, however, are not solely depended upon to performthis function, but springs 17 attached to the hopper bottom and to thelower portions of the hinged sides forcibly pull the hinged sideportions to the bowl. Leak-proof joints between the hinged side portionsand the bowl are insured by providing the contacting edges with tonguesand grooves, as shown in Fig. 1, and lining the groove with a rubber orother gasket 18.

Around the neck of the cuspidor' is a rotatable ring 19 of suflicientdiameter to inclose and freely move over the extensions 13a. This ringis shown to be longitudinally curved, with the convex face arrangedoutwardly to bear at the top and bottom edges of the funnel and bowlrespectively. The ring 19 is provided with handles 20 by which it isrotated, and also with cams 21 on its inner face at diametricallyopposite points, each cam having a central notch and designed to pass tothe outside of the extensions 13a and thereby spread the hinged sideportions 13 apart and hold them open against the tension of the springs1G and 17, as when the cuspidor is being washed out. The free passage ofthe cams to the outside of the extensions 13a is insured on revolvingthe ring, by reason of the inwardly-inclined end portions of theextensions above referred to. The notches in the center of the cams areengaged by the central portions of the extensions 13a, as shown in Fig.6, thus freely retaining the ring in place when the hinged side portionsare fully opened. When the hinged side portions of the cuspidor areopened, the rapid discharge of the contents and thorough cleansing ofthe cuspidor is insured by the hopper bottom 15.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. A cuspidor having side portions hinged at the to-p to swing outwardlyat the bottom, and provided with a hopper bottom inclining from thecenter of the cuspidor toward the hinged side portions.

,2. A cuspidor having movable side port-ions, and a revoluble memberencircling the cuspidor having means to move the side portions to anopen position.

8. A cuspidor having a side portion hinged to swing outwardly at thebottom, means tending to force the hinged side port-ion closed, and arotatable ring arranged around the neck of the cuspidor, having means toforce the hinged side portion open against the tension of said means.

4. A cuspidor havinga sideportion hinged at the top to swing outwardlyat the bottom, and provided with an extended portion above the hinge,and a rotatable ring surrounding the neck of the cuspidor, having a camto engage the extension of thehinged side portion and force the sideportion open.

5. A cuspidor having side portions hinged at the top, each side portionhaving an eX- tension above its hinge, a hopper bottom incliningdownwardly from the center toward each hinged side portion, springstending to force the hinged side portions closed, and a rotatable ringencircling the neck oi the cuspidor, having cams to engage with
